Clin Exp Pediatr. 2000;43(11):1465-1472.   Published online November 15, 2000
Purpose : Congenital chloride diarrhea(CLD) is an autosomal recessive disease characterized by life-long watery diarrhea of prenatal onset with high fecal Cl－ concentration. Recent studies have revealed that the protein product of the down-regulated in adenoma(DRA) gene is an intestinal anion transporter molecule and causes CLD when mutated. We investigated the clinical characteristics of CLD in Korean infants in order...

Plasma Somatomedin C Levels in Normal Children
Bo Young Yun, Hoan Jong Lee
Clin Exp Pediatr. 1992;35(11):1493-1500.   Published online November 15, 1992
Somatomedin C, the insulin-like growth factor I is suggested to mediate the growth-promoting effect of growth hormone. Sm-C, mostly bound to plasma protein forming an IGF-I protein complex, is slowly cleared from plasma and thus its plasma concentration is quite constant. A single sampling of blood for Sm-C is sufficient for the measurement of its concentration. For the evaluation of...
